'10 oil when: it may concern ie it known that i CHARLES Raoatnpa citizenof the United States, residing); at .iutialo. in the county or Erie andState of New York, have invented certain new and useful Improvements inTire-lnflators; and .1 do hereby declare the tollowingto be a full,-clear; and exact description of the in vcntion, such as Will enableothers skilled in the art to which it appertains to make and use thesame. I f

This invention relates tonew and useful improvements in tllliOIHO'fillCtire inflating devices, and has for its object the provision of a deviceof the above character, which is adapted to inject air into the tires ofa motor vehicle, when said vehiclesare runng.1

Another object of my invention is the provision of a device of the abovecharacter, which may be easily and quickly applied to the ordinary typeof motor vehicle wheel without materially changing the construc tion ofthe same. Still another object. of my invention is the provision of sucha devict iich may be thrown into and out of opera at. will of the driverwithoutthe necess t; of stopping the car. \Vith the above and otherobjects in view I now proceed to describe my invention in the followingspecification, and accoin 'ianying drawings, 1n-which v Figure 1 isaplan view of my improved 85 tire inflator, Fig. 2 is an edge view of thesame, Fig. 3 is a longitudinal sectional vie v taken on line 3-3 at Fig.1, Fig. -'lis aplan View of my improved intlator. showing the same as itwould appear when looking at -30 the side opposite Fig. 1, Fig. 5 is alongitudinal sectional view of the casing,- which is used in theconstruction-of. my inflatingdevice. Fig. (3 is a plan view of? theplate used in conjunction with my inflating device, Fig. 7 is a.longitudinal sectional view taken on line 7 -7 at Fig. 6, Fig. 8 isatotal view of the inner ring, and Fig. 9 is a total view or the packing,

Referring to the drawings and the nu- 0 morals of reference,1 indicatesthe main ring, forming a body portion of my improved inflat-inc; device.This ring has formed there'- on and extending outwardly therei'ron'i thething": 2, which is provided with screw threaded apertures 8, the useo'l' which will be more fully hereinafter described.

Specification of Letters Patent.

.with the apertureslaterally Suitable lugs tare formed integral with theenter periphery of the ring 1 and are pro vided with the apertures 5 bymeans of which the device is adapted to be secured to the wheel of themotor vehicle. These lugs 5 are preferably positioned at diametricallyopposite points around the periphery of the rind and are equallydistanced from each ether, as will be clearly seen upon referring to thedrawings.

A cooperating ring (5 of substantially the same dimensions as the ring 1is provided 7 These apertures 7 are preferably located in such a mannerthat they register with the apertures 23 formed in the annular flange 2,suitable screws 8 are adapted to be inserted through the apertures 7 andinto the apertures 3 and therei by hold the ring 6 in position on thering 1,' as 15 clearly illustrated in Figs. 2 and 3.

"The flange 2 formed on the ring 1 is preferably provided with theaperture S), which extends radially thercthrough and is adapted toreceive the air outlet pipe 10, which is connected to the valve of avehicle tire by any suitable means. The internal ring 11, which is usedin conjunction with the rings 1 and i is provided with the internallyscrew threaded aperture .12 which is adapted to reeeive the end; of thepipe 13', which inturn leads to a suitable source of air supply. Thepacking ring 14 is preferably segnlental in cross section, as will beclearly seen upon reterring'to Fig. 3, and its latc 'al edges areadapted to fit snugly between the rings 1 and (3, this packing ringbeing adapt ed to form an air tight'chamber between the, flange Q-andthe'ring' 11, which extends aunularly around 'the outer periphery of thering 11. A suitable aperture 15 is provided' in the rinq'll and isadapted to receive the screw threaded shank or the lubricating deviceindicated by the numeral 16, which is adapted to keep the partsstiflieiently oiled and thereby prevent undue wear, which may causeleakage the'air during the time the tire is being inflated. Formedintegral with the ring 11 and extending inwardly with relation thereto'1 preferably. provide the arms 17, which=- are substantiallydiametrically opposite each other and are provided with the apertures 8by means oi which said arms are adapted o be secured to the axis of thechicle upon which the device is be.iu'; uised.

It will beclearlv seen troin the tore 'oin thatwith my improvedinflating device, the tires of a motor vehicle may be pumped at alltimes regardless asto whether or not the said vehicle is running. Itwill be obvious that the air entering through the pipe 13 and thestationary ring 11 will pass into the annular chamber A,-which beingprovided with the outlet Stormed in the outer ring 1, will permit theair contained in the chamber to flow outwardly through the pipe 10 andinto the. tire of the vehicle. Thus it will be seen thatthe tire may beinflated regardless as to what position the wheel may be in andalsowithout regard as to whether or not said wheel is in motion.

Whilein the'foregoing I have shown and described the preferredembodiment of my invention, I wish it to be understood that I may changethe specific arrangements of parts without in any way departing from thespirit and scope of my invention as defined by the appended claim.

l laving thus described my invention, what I claim is:

Tn a device of the eharacten described a ring, an annularextensioirformed on said ring. said annular extension being of lessthickness than, the width of the ring'and mosses having screw receivingapertures in the periphery thereof, said annular extension also havingan outlet-aperture. in the periphery thereof, ears formed integralwiththe ring and extending outwardly therefrom to provide means to connectthe ring to the sp'ol of a vehicle wheel, an inner rotatable ringmounted within the annular extension-and spaced therefrom-t0 form achamber, said inner rotatable ring having an air inlet aper turetherein, arms at diametrically opposed points extending into the ringand forming a means to secure said ring to the axle of a vehicle, acover plate having screw receiving apertures therein, adapted toregisterw'ith the internally screw threaded apertures in the annularextension, and a packing ring secured to the rotatable ring and adaptedto fric-tionally engage the side walls of the chamber to prevent airleakage when the device is in use.

' In testimony whereof I atlix lay signature in presence of twowitnesses.
